Display screen and producing method thereof

Abstract

A display and manufacturing method thereof. In the display panel (1), as for the plurality of colors display part (2), one display element (2A) is formed by a plurality of unit display regions (20R, 20G, 20B) composed of different colors, and as for the single color display part (3), one display element (3A) is formed by a single color of one unit display region (30). Then, in the display panel (1), the area of the unit display region (30) in the single color display part (3) is formed larger than those of the respective areas of the unit display regions (20R, 20G, 20B) in the plurality of colors display part (2). Thus, to keep life balance of a light emitting element at the whole display region in the display panel which is divided into a single color display part and a plurality of colors display part on the same substrate.

Description

technical field [0001] The invention relates to a display screen and a manufacturing method thereof. Background technique [0002] As displays, various displays including liquid crystal displays have been put into practical use, but displays using self-illuminating light-emitting elements can keep power consumption low compared to liquid crystal displays using backlights. And attracted much attention. As display screens using such self-illuminating light-emitting elements, there are various display screens such as PDP (Plasma Display Panel) and FED (Field Emission Display). In terms of screen curvature, the organic EL (Electroluminescence) display, which has more advantages than other displays, has attracted more attention. This organic EL display panel is composed of an organic EL element formed by sandwiching an organic layer including a light emitting layer between a pair of electrodes. [0003] In such a display screen using self-luminous light-emitting elements, a di...

Problems solved by technology

In this way, when a static image such as a pattern is displayed on a multi-color display part, there is a problem that good display performance cannot be obtained due to a decrease in resolution.

[0008] In addition, in the conventional example, since the monochrome display part has unit display regions formed at the same intervals as the multicolor display part, if the overall resolution is increased, the part that does not emit light between the unit display regions in the monochrome display part increase, leading to a decrease in aperture ratio

If the output level of the monochrome display part is increased to compensate, the life of the light emitting element of the monochrome display part will be shortened.
